The 200 million is definitely partly or all customers' money, otherwise they wouldn't have paused the withdrawals and yeah, it's 2023 and people are still too foolish to keep all their money and life savings in custodial centralized exchanges/services. They never totally learned anything from evens as recent as the FTX or Celsius network scandals

I hope the mixin safe team took notes when a lot of members were not comfortable with how the services operated. Registering using phone numbers, the mixin messenger app centralized nature etc. maybe the hack will be an eye opener.
